Email Class SSL verification bug on PHP 5.6 (SSL3_GET_SERVER_CERTIFICATE)

@Avenirer Could you be more specific?

@Rômulo and @Rufnex, I solve this problem, and I wrote about in this post on my blog at: here [PT-BR]
Its a simple problem about openssl.cafile set on php.ini (PHP 5.6+)

That error is related to the firewall settings of your server... I think... and not to CodeIgniter.
